Second Benefit of Marriage...
Second Benefit of Marriage: The second benefit is that the husband and the wife jointly (but with division or responsibilities) perform the tasks which they are faced with in establishing a family. And each finds his or her fulfilment in the other. As explained earlier, woman is not fit to earn livelihood; man is not fit to manage domestic affairs. Marriage binds them to make up each other's deficiencies, so that the family may prosper.
The man will spend his energies in earning a livelihood for himself and his family. The woman will manage the domestic life with that income. Allah has reminded us of this very point in these words And marry those among you who are single, and the virtuous ones among your slaves, male and female: if they be in poverty, Allah will make them rich by His Grace; for Allah is abundantly-giving, All-knowing.
( Qur'an, 24:32) It is for this reason that al-Imam Ja'far as- Sadiq (a.s.) said: "The sustenance is with women and dependants." Domestic science is the natural preserve of women, and by their efficient management they can make the money stretch far. Modern non-Islamic societies have laid the foundation of matrimony on only this cooperation between husband and wife, while in Islam it is a secondary, not the primary, benefit.
Marriage, according to present day societies, is a co-operative venture, albeit much narrower in scope than other such institutions, like a municipality or a club. It is for this reason that modern laws do not pay any attention to the rules of chastity etc. This inadequate foundation - cooperation in life - has given rise to a vast multitude of social problems and has created chaos in domestic life, because it is not in complete harmony with realities of creation and nature.
Man is a social animal, no doubt. Everyone cooperates with everyone else, dividing the labour and work according to one's aptitude. But this factor requires cooperation between any two persons; it does not specifically call for cooperation between a man and a woman. Therefore, it is a weak foundation on which to build the edifice of matrimony.
If marriage were only a co-operative institution, there would be no need of any special rule for matrimony; the general rules governing associations and co-operative societies would be enough. It would negate the virtues of chastity and fidelity, nullify the concept of legitimacy and affinity, and abrogate the rules of inheritance - as some "advanced" societies have done.
